I just don't fire too many of them in one batch, and if I have the slightest suspicion that they have not fully sintered, I repeat the second phase. With cork clay, I hold up to one hour at the first phase, letting it all burn. Hi Kim,

And for cork clay based forms, do you do it after the first firing fires off the cork? How do you fill a closed hollow form or one with small stringing holes with carbon?

I have fired BronzClay and CopprClay about 4 - 5 times in my Rio Blue front load PMC kiln. (Is this a Paragon SC kiln?) No problems with the carbon degrading, no sintering problems either. I've fired both on a full ramp and hold as well as your schedule (fire in the box, cool, then fire again). I do NOT have anything else running on the circuit when I fire.

I used the Rainbow carbon with both copper and bronze and it worked great. WholelottaWhimsy is now my source for carbon. I use a front loading brick kiln. I follow Hadar's schedule for a top loading brick kiln. Thanks, Hadar, for all your help! Lin I’ve finally been successful with my firing.

It went great. I fired 7 bronze pieces, medium sizes, including 2 hollow forms, using your methods. I did pre-fire the carbon at full ramp to 1516F for 15 minutes. Thanks so much for all the research you're doing for us. Hope to see you soon! Jonna Hi, Hadar, I just completed my first firing with Whole Lotta Whimsy’s Rainbow carbon. It went great.

While, I'm only just getting started, I've fired with the same coconut derived carbon for about 9 firings with no problems in a Paragon SC kiln.
